ABSTRACT:
A clutch device which can perform the plural functions required in an automatic transmission is provided. As a result, it is possible to reduce the number of clutch devices required to obtain the desired gear ratios and shift operations. The clutch device, according to the present invention, comprises a pair of members spaced on a common axis and relatively rotating around the common axis, a variable length coupling member disposed on the common axis between the relatively rotating members and having a pair of cam members, and a piston member selectively pushing the variable length coupling member toward one of the relatively rotating members. The piston member causes frictional engagement between one end of the variable length coupling member and one of the relatively rotating members so that the cam members relatively rotate and cooperatingly generate a cam force, in an axial direction, which elongates the variable length coupling member and couples the relatively rotating members. The piston member pushes the variable length coupling member even when the direction of the relative rotation of the relatively rotating members is reversed.
